I am a new to the server world, and I need some assistance setting one up.
Here is my question: How can I host multiple websites on one server...with one public IP address...with Apache, without having to have registered domain names for each website?
I would like to be able to type in my public IP address from anywhere...and have the ability to view any particular website on the server. Perhaps...by typing this into a browser address bar for one website--http://xx.xxx.xxx.x:80, and this into the address bar for another website--http://xx.xxx.xxx.x:81.
I'm not sure how to do this; I haven't been able to find tutorials or guides for this goal.
I am using Apache 2 on Ubuntu Server 12.04. My server computer is going through a home router (is using the router's public IP address).
Any advice is greatly appreciated.
